SASH CONSTRUCTION Filed July 21, 1928 vwntoz Z! APONMQUL/J /7/ MEM @www @wm y W Patented Jan. 19, 1932 rarenrrrice AARON M ARGULIS, OF BROOKLYN, NEIW YORK SASH CONSTRUCTION Application led July 21,

This invention relates to sash constructions and in particular to the type which is adapted for the cleaning of the windows without the necessity of getting outside the window.

A particular object or" the invention is to provide a window sash construction which is supported by. suitable spring strips arranged Vto be supported on a spring roller to permit easy movement oi' the sashes.

A still further particular object of the invention is to provide a tongue and groove strip between the vsasnes and slide pieces secured thereto which will permit the sa'shes to be moved pivotally in the sash trame so that both sides of the window may be cleaned.

A still further object of the invention is to provide tongue and groove connection between the slide piece and the sash so that the windows will be weather-proof.

To enable others skilled in the art to fully comprehend the underlying features of my invention that they may embody the same in the various modifications in structure and relation contemplated, drawings depicting a preferred form have been annexed as a part of this disclosure and in such drawings, similar reference characters denote corresponding parts throughout all the views, of which,

Figure 1 is a view in iront elevation ot a window sash construction. a part thereoi1 being shown in section to disclose the spring housing and method of supporting the sashes within the Jframe.

Figure 2 is a view in end elevation ot the sashes, the lower one being shown in its pivotal position.

Figure 8 is an enlarged, fragmentary section of the upper end ot the sash trame at one side thereof illustrating the spring housing and method ot attaching the end of the spring strip to the slide piece, and

Figure 1l is a plan view in section taken through one side of the sash and sash iframe` and illustrating` how the tongueand groove members are nplied to the slide piece and sash to permit pivotal operation of the latter.

Referring to the drawings in detail, 5 indicates a sash frame o'r' the usual construction which is provided acljface nt its upper ends and at opposite sides thereof with openings 6 in 1928. Serial No. 294,461.

which are disposed, the springhousings v7. These housings are provided with extensions 8 which tit into the sash frame 5 in an undercut slot and are retained in position through the medium of the screws 9.

In view of the tact that bot-hV sashes are of identically the same construction and both sides of the window are also of identically the same construction, it is believed necessary to only describe in particular, one set of the eo operating mechanism. The lower sash is indicated by the numeral 10and the upper sash by the numeral 11, the sashes consisting of the usual frame piece 12 and glass 13 and the side edges of the sash frame piece 12 are covered 35 by a longitudinal groove piece 13a madeof metal, the groove therein being indicated by the numeral 14 and being of a suitable depth to accommodate snugly the tongue 15 formed yin the tongue strip 16 which is of identically i8 the same construction as the groove strip 13, the edges of each being turned over and secured in any manner to the side of the sash piece 12 and slide piece 18. The slide piece is of the same length as the sash piece 12, and 'X5 as before noted is provided at one of its edges with the tongue strip 16. The slide piece is p further provided with a recess 19 from which extends a bore 20, this bore 20 connecting the recess 19 with the tongue strip 16 and being so arranged to accommodate a coil spring 21 which is positioned about a bolt 22 which is threaded as at one end 23 into the sash piece 12, the opposite end thereof being threaded to receive the cap nut 24 against which the outer end 'of the spring 21 presses, it being quite evident that this cap nut may be used to adjustthe tension on the spring and the lower end of the spring'bearing against the tongue portion of the strip 16 will. have a tendency to maintain it in its extended position under all conditions.

The metal of which the tongue and groove strips4 are made may be more or less of a resilient nature so that the longitudinal tongue 15 may snap out of and into the groove lll when the frame piece 12 is swung about the pivot point, namely, the bolt 22 one ot each of which is positioned at opposite sides of the center ot the upper and lower sashes, the

of the sash frame construction. These slots` being provided for travel of the sashes.

It is also evident that these slide pieces may have free movement in the grooves 29 when the sashes are t0 be raised or lowered.

The spring strip 25 is made of spring metal which will have a tendency to wind up the spring roller 26 when the Window sash is In this respect, the usual counterweights are dispensed with and the necessity for frequent replacement of the worn out sash cords is eliminated.

Itis also quite evident that with the spring connection of the slide piece and sash frame piece 12 that the two will be securely joined together and will prevent the admission of any moisture or cold air through the construction. These grooves and tongue strips act as weather strips when the sashes are in their normal position.

It is quite evident also, that by this Construction, the sashes may be revolved about their pivot point and the windows may be readily cleaned without the necessity of the cleaner getting out upon the window sill.

It' is also evident that in a construction of this character, the parts may be applied to window sashes in existence, it being simply necessary to remove the sash cord pulleys and substitute the spring housing andr to cut the sash frames to provide slide pieces which are joined in the manner indicated to provide pivotal lioining of the sashes.

While I have illustrated and described my invention with some degree of particularity, I realize that in practice various alterations thereinxmay be made. I therefore reserve the right and privilege of changing the form of the details of construction or otherwise altering the arrangement of the correlated parts without departing from the spirit of the invention or the scope of the appended claim.

Having thus described my invention what I claim as new and desire to secure by United States Letters Patent is Y A window sash construction, a channeled sash frame, a sash, a grooved strip covering an edge of said sash and extending the entire length of saidV edge, a slide piece having an opening therein at substantially the horizontal* center of the sash, a iuted strip covering an edge of the slide and extending the entire length of said edge, the flute being arranged to seat in the groove of said sash strip, a bolt having a hook end secured in said sash and passing into the opening of the slide piece, said hook being arranged to receive the end of a supporting member and to constitute a pivot for the sash, a nut threaded to said bolt, and a tension spring on the bolt positioned between the luted slide strip and said nut for yieldably maintaining the sash and slide strip 1n contact.

In testimony whereof I aix my signature.
